Sexually Transmitted Infections

This page provides and overview to some of the most common sexually transmitted infections. For information on testing, please see STI Testing. For information on preventing the transmission of STIs, please see Safer Sex. There are three types of STIs: viral, bacterial, and infestations.

Fungal infections
While not technically STIs, this infection can be passed through sexual contact or by sharing sex toys.

Yeast Infection (Candida)
A vaginal yeast infection is a common fungal infection caused by overgrowth of Candida, naturally occurring yeast. Yeast is normally found in a woman’s vagina in small numbers, but sometimes they can multiply and change the normal balance of bacterial growth. When the fungi begin to grow in excess, they may develop into candidiasis.
